Summary by CodeRabbit

Release Notes

  • New Features

    • Added relay-compatibility standardness checks for VTXOs, with richer, location-aware error details.
    • Introduced NonStandardOutput/check_standard() to explain whether failures are due to dust limits or non-standard scripts.
    • Added a new exit error type for non-standard VTXOs.

  • Bug Fixes

    • Unilateral exit initiation now refuses non-standard VTXOs before persisting state, helping avoid CPFP fees for exits likely to be rejected.

  • Documentation / Chores

    • Updated REST/OpenAPI model docs and schemas for the new exit error variant.
    • Added/expanded unit tests for standardness scenarios.
